ATTACKING A VESSEL AT ANCHOR BY PASSING ON EITHER SIDE DETERMINED UPON,
COMING UP FROM THE STERN.
In this case, the torpedo is launched when on the quarter of the vessel
attacked, as at A, the tow-rope left slack. After steaming ahead some
distance, hold fast the tow-rope, when, by continuing to steam on,
the torpedo will diverge into contact with the bottom of the vessel
attacked, as shown in the drawing. _When skilfully performed_, the total
destruction of the enemy is certain, since the torpedo is springing
from a depth to the surface, and will, in consequence, strike near the
keel. The torpedo vessel can pass at her greatest speed, and, if thought
necessary, near enough to clear away any of the ordinary obstructions,
such as booms, nets, &c.
